;;; Band Limited ImPulse generator. All harmonics have equal
;;; amplitude.

;;; This is the equivalent of 'buzz' in MusicN languages. WARNING:
;;; This waveform in its raw form could be damaging to your ears at
;;; high amplitudes or for long periods.
 
;;; Implementation notes: It is improved from other implementations in
;;; that it will crossfade in a control period when the number of
;;; harmonics changes, so that there are no audible pops. It also
;;; eliminates the divide in the formula by using a 1/sin table (with
;;; special precautions taken for 1/0).  The lookup tables are
;;; linearly interpolated for better quality.
 
;;; The number of harmonics may be lowered internally if it would
;;; cause aliasing.
